| Abstract: | In this paper, on the engineering background of the Beijing-Shanghai high-speed railway bridge 3,4 pier platform big volume concrete construction, the author introduces large-volume concrete anti-crack construction scheme, construction preparation, construction technology and teehnieal measures to prevent concrete from cracking in the silty clay. The technology accumulates some successful experience for a mass concrete construction of foundation platform prevention of cracking, and it can provide some references for similar engineerings. |
